i bought a pc back in march about two months ago it started developing a fault, i got in touch with the tech support for the firm and they sent an engineer out.....so the guy went and came, the pc was working.....20 mins later same fault
so again i rang up the tech support and told them i want a new unit which they refused many times... so they sent the same technician out again this time replacing practically everything, guess what same fault
so this time the pc was sent away, i recieved it back yesterday, (note it has a three year warrenty, so i set it up last night thinking all would be ok......10 mins later same fault
except this time the os wont load
so im in a situation where i want a new unit, so what is my legal stance on this ? can i demand a proper replacement or are they required to legally fix it how they see fit ?
